Nursing Elites

1. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:

• A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
• B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
• C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
• D. To lower blood glucose by stimulating the release of insulin

Correct answer: A

Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.

2. A client with Graves' disease is being educated by a nurse about her prescribed medications. Which of the following statements by the client indicates an understanding of the use of Propranolol in the treatment of Graves' disease?

• A. Propranolol helps increase blood flow to my thyroid gland.
• B. Propranolol is used to prevent excess glucose in my blood.
• C. Propranolol will decrease my tremors and fast heartbeat.
• D. Propranolol promotes a decrease of thyroid hormone in my body.

Correct answer: C

Rationale: The correct answer is C. Propranolol is a beta-adrenergic antagonist that is commonly used in Graves' disease to decrease symptoms such as tremors and fast heart rate. Choice A is incorrect because Propranolol does not increase blood flow to the thyroid gland. Choice B is incorrect as Propranolol is not used to prevent excess glucose in the blood. Choice D is also incorrect as Propranolol does not directly decrease thyroid hormone levels in the body.

3. When teaching a client with a prescription for long-term use of oral prednisone for chronic asthma, the nurse should instruct the client to monitor for which of the following adverse effects of this medication?

• A. Weight gain
• B. Nervousness
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: The correct answer is weight gain. Weight gain and fluid retention are common adverse effects of oral prednisone due to sodium and water retention. Patients on long-term prednisone therapy should be advised to monitor their weight closely and report any significant changes to their healthcare provider. Choice B, 'Nervousness,' is not typically associated with oral prednisone use. Choice C, 'Bradycardia,' refers to a slow heart rate, which is not a common adverse effect of prednisone. Choice D, 'Constipation,' is not a typical adverse effect of oral prednisone; instead, gastrointestinal disturbances like increased appetite or even peptic ulcer disease may occur.

4. When teaching a client how to use nitroglycerin transdermal ointment for angina, which instruction should the nurse include?

• A. Remove the prior dose before applying a new dose.
• B. Rub the ointment directly into your skin until it is no longer visible.
• C. Cover the applied ointment with a clean gauze pad.
• D. Apply the ointment to the same skin area each time.

Correct answer: A

Rationale: The correct instruction is to remove the prior dose before applying a new dose. This helps prevent toxicity by ensuring the client does not inadvertently apply an excessive amount of nitroglycerin.

5. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following herbal supplements should the nurse instruct the client to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism pathways, potentially leading to decreased anticoagulant effects. Therefore, clients on Warfarin therapy should avoid St. John's wort. While echinacea, garlic, and ginseng are also herbal supplements that can interact with Warfarin, St. John's wort is particularly known for its significant impact on Warfarin metabolism. Echinacea may increase the risk of bleeding when taken with Warfarin, garlic may potentiate the anticoagulant effects of Warfarin, and ginseng may also increase the risk of bleeding. However, St. John's wort is the most crucial to avoid due to its significant impact on Warfarin metabolism.
